Vue 引入G2图表

安装G2依赖

npm install @antv/g2
npm install @antv/data-set vue-ge

在Vue  main.js文件中引入G2

import G2 from '@antv/g2'
Vue.use(G2)

模板中使用完整代码（柱状图）

<template>
  <div id="c1"></div>
</template>
<script>
    export default {
        name: "spectaculars",
        data(){
            return{
                basicColumnChartProp:{
                    data:[{ genre: 'Sports', sold: 275 },
                        { genre: 'Strategy', sold: 115 },
                        { genre: 'Action', sold: 120 },
                        { genre: 'Shooter', sold: 350 },
                        { genre: 'Other', sold: 150 }],
                    container:'c1',
                    width:700,
                    height:600
                },
            }
        },
        methods:{
            test(){
                const data = this.basicColumnChartProp.data;
                const chart = new G2.Chart({
                    container: this.basicColumnChartProp.container,
                    width : this.basicColumnChartProp.width,
                    height : this.basicColumnChartProp.height
                });
                chart.source(data);
                chart.interval().position('genre*sold').color('genre')
                chart.render();
            }
        },    
        mounted() {
          this.test();
        },
    }
</script>

在补充一下世界地图（当初项目需求找了G2的地图,感觉API文档有些东西没说明白,这里记录一下）

                    container:'c1',
                },
            }
        },
        methods:{
            test(){
              fetch('src/views/dataCenter/data/world/countries.geo.json')

fetch这个地方官网引入的是文件目录,不是具体的json文件,使用的时候找不到文件
fetch引入的json这里是本地的,其次G2官网提供的远程githup地址获取不到这个json文件
fetch引入json文件的路径，不是你当前文件到该json的路径，而是index.html到该json文件的地址
